Description

Drives for marine vessels

technical field

The invention relates to a drive device for a marine vessel and a marine vessel provided with such a drive device.

Background technique

A marine vessel such as a powerboat may be equipped with a propulsion system in the form of an inboard/outboard drive comprising an outboard drive unit equipped with a propeller arranged on the outside of the transom of the marine vessel and also the arrangement of the drive Additional components (eg power sources) arranged inside the transom of the marine vessel and thus inside the hull. Openings in the transom allow various connections (power, control, hydraulics, etc.) between the outboard drive unit and the power source and other components of the drive located inside the vessel. At least a lower part of the outboard drive unit is generally arranged to pivot about a vertical axis to allow steering of the watercraft.

Traditionally, such drive means include a power source in the form of an internal combustion engine operatively connected to the drive unit by a drive shaft extending through an opening in the transom. Recently, various variants of drives have been proposed in which, instead or in addition to conventional engine-driven shaft drives, electric motors are arranged for driving the propellers. This electric motor (in the type of marine vessel concerned here) is connected to a relatively large power source arranged inside the marine vessel in the form of a battery, a fuel cell, or a generator driven by an internal combustion engine (or some combination of such power sources) . Where the electric motor is arranged in the outboard drive unit, cables are arranged through the opening in the transom, thereby electrically connecting the power source and the electric motor.

US5688152 and US5755604 disclose examples of conventional drives of the above-mentioned type in which a drive shaft extending through an opening in the transom is operatively connected between an internal combustion engine arranged inside a marine vessel and an outboard drive unit.

As shown in US Pat. No. 5,688,152 and US Pat. No. 5,755,604, drives of this type comprise a support carriage arranged to the transom at its opening. The function of the support carrier is to secure and support the outboard drive unit to the transom and to take up thrust and steering forces eg from the outboard drive unit when the drive unit is used to propel the marine vessel. In case the (subsea part) of the outboard drive unit hits a stone or other obstacle during operation of the vessel, the support carrier should also be able to withstand the impact forces.

The support carrier is exposed to considerable forces and loads, and these forces are transmitted to the transom on which the support carrier is arranged. Although various designs of transoms and support carriers have been proposed over the years, there is still room for improvement in the transfer of forces from the outboard drive unit to the transom.

Contents of the invention

It is an object of the present invention to provide a drive arrangement for marine vessels which reduces the transfer of loads and forces from the outboard drive unit to the transom.

In a first aspect, the invention relates to a drive arrangement for a marine vessel, the drive arrangement comprising an outboard drive unit provided with at least one propeller, wherein the outboard drive unit is configured to arrange On the outside of the transom of the marine vessel and connected to other components of the drive device disposed inside the marine vessel via an opening in the transom; and a support carrier configured to be disposed in the opening in the transom place for fastening and supporting the outboard drive unit so as to withstand the thrust and steering force from the outboard drive unit when the drive device is installed and used to propel a marine vessel.

The drive device also includes a support frame structure configured to be fixed to a support hull structure disposed on the inside of the marine vessel forward of the transom, the support frame structure further configured to The structure either extends aft along the supporting hull structure to said opening in the transom, wherein the supporting carrier forms part of the supporting frame structure or is fixedly secured to the supporting frame structure.

Accordingly, the outboard drive unit is supported by a support carrier which then forms part of or is fixedly fixed to the support frame structure which is then fixed or intended to be fixed to a The supporting hull structure on the inside of a ship. This allows loads and forces from the outboard drive unit to be transferred to the supporting hull structure during operation of the marine vessel rather than to the transom as in conventional drives.

The main effect of this is to simplify the design and production of the vessel as the transom no longer needs to support steering, thrust or collision loads. In turn, the transom (and possibly other parts of the hull) can be made thinner and lighter. Regardless, a supporting hull structure is generally required for supporting the power source and for supporting the hull itself. The supporting hull structure may comprise one or more supporting beams, stringers extending along the bottom of the marine vessel in its longitudinal direction. However, other types of supporting hull structures are also possible, such as uniform support areas arranged in the bottom structure of the hull and/or supporting structures arranged at or along the side walls of the hull.

Another effect of the drives of the present disclosure is that marine vessel drive train manufacturers are able to provide pre-tested, pre-assembled and pre-packaged power transfer assemblies comprising both an outboard drive unit and a power source, wherein the The drive unit and the power source are operatively connected and are both carried by the supporting frame structure (possibly with damping elements between the power source and the frame).

Preferably, the outboard drive unit should be relatively easy to detach from and reattach to the support carrier/frame structure and power source, allowing The power transfer assembly is effectively reassembled while inside the vessel (preferably while carrying the power source) and the outboard drive unit is to be reattached to the carrier and power source from the outside of the vessel. This simplifies the production of the vessel at the boat production site. With respect to the drive, apart from securing the supporting frame structure to the supporting hull structure, it is more or less only necessary to form a hole/opening in the transom (the hole/opening is preferably adapted in size and shape to the supporting carrier ), and reattach the outboard drive unit. Thus, the drive unit does not require the transom to be designed such that the transom can withstand thrust, torque, shock, steering or trim loads.

The support frame structure can be designed in different ways. In one example, the frame structure includes a forward section configured to be secured to a supporting hull structure and further configured to carry batteries, an engine, or other power source. The frame structure may comprise a rear/stern section provided with a support carrier, such as a ring member, facing the transom (when the frame structure is arranged in a marine vessel), And when the frame structure has been installed in the marine vessel (and in case the opening has not been formed in the transom before installing the frame structure, then when the opening has been formed in the transom), the support carrier becomes opposite The transom and openings in the transom are properly positioned. The opening is preferably adapted to the size and shape of the support carrier and vice versa. The support carrier may extend at least partially through the opening in the transom. Alternatively, the drive means may be arranged such that the support carrier becomes located inside (the opening in) the transom. The transom may be provided with more than one opening relating to the drive means.

In one embodiment, the supporting frame structure comprises at least one supporting member configured to be fixed to a supporting hull structure comprising longitudinal stringers arranged in the bottom of the hull of the marine vessel. The at least one support member may be a plate which may be secured to two or more spaced apart longitudinal stringers. As an alternative to such plates, the supporting frame structure may comprise one or more elongated supporting members, each arranged to extend along and secured to a corresponding stringer.

Various control units and other components may also be arranged to this support frame structure.
